A Novel Model to Explain Extreme Feather Pecking Behavior in Laying Hens.

abstract：:A model to analyze resemblances of twins and parents using LISREL is outlined and applied to sports participation and heart-rate data. Sports participation and heart rate were measured in 44 monozygotic and 46 dizygotic adolescent twin pairs and in their parents. Genetic factors influence variation in both sports beha...
